Error code low pressure system

If you see any either E1-19, E1-18,F9, F22 or HO2.07 error codes, this indicates a low-pressure system.



Have a look at the pressure gauge on your boiler and if it is below 0.75 and in the red zone, then you can have a go at topping up your boiler pressure to try and get it working again. We understand that trying this for the first time might be a little daunting but we've created our simple and easy to follow step by step guides so you can give it a go!

There's 2 types of what we call filling loops on our boilers. These are what you use to top up your boiler pressure. Have a look underneath your boiler. You should be able to see either wheels or levers to top up the boiler pressure on your filling loop. They will be connected to a flexible bit of braided pipe.

If you can't see these on your boiler, it's likely you have a Baxi Megaflo boiler, and you'll find the filling loop on your hot water cylinder tank in the airing cupboard.
